Sanding Belt
Abrasive
belt is a belt-shaped tool that can be ground and polished, which is made by
bonding abrasives to flexible materials such as paper and cloth with a binder.
It is a main form of coated abrasives. Its basic composition is: base material,
abrasive and binder, collectively called the three elements of abrasive belt.
Abrasive belt is the main tool of the sanding process. Abrasive belt grinding
is a soft grinding method, which is a compound processing abrasive tool with
multiple functions of grinding, grinding and polishing.
Abrasive
tools are tools for grinding, grinding and polishing. Most of the abrasives are
artificial abrasives made of abrasives and bonding agents, and natural
abrasives are also directly processed from natural ore. In addition to being
widely used in machinery manufacturing and other metal processing industries,
abrasive tools are also used in the processing of non-metallic materials such
as food processing, paper industry and ceramics, glass, stone, plastic, rubber,
and wood.
Abrasives
are divided into natural abrasives and artificial abrasives. All materials that
can be used for grinding or grinding in nature are collectively referred to as
natural abrasives.
Natural
abrasives mainly include: natural corundum and garnet
Artificial
abrasives mainly include: white corundum, brown corundum, silicon carbide,
zirconium corundum, synthetic diamond, cubic boron nitride.
How
to choose a suitable abrasive belt and further improve the smoothness and
flatness of sanding is a very important issue in the use of abrasive belts. Due
to the differences in the three major components of abrasive belts and various
characteristic factors, abrasive belts can be divided into many varieties
according to different grinding objects, grinding conditions and grinding
requirements. The following is the classification of abrasive belts according
to abrasives. Different abrasive belts are suitable for different products. The
following types of belt operations are: automatic grinding, mechanical hand
grinding, desktop grinding, and manual tool grinding.

Index: Since the birth of China's first synthetic diamond in the 1960s, China's super-hard materials and products industry has taken root and thrived, occupying the throne of the world's superhard material powers. In the course of nearly 50 years of development, Huaxia Shenzhou has created one diamond after another, they lead the direction of the entire super-hard industry, Eshin Diamond Materials Co., Ltd. is one of the most dazzling diamonds. Well-developed first-class brand Exin Diamond Material Co., Ltd. was established in 1992, specialized production of diamond raw material, diamond and diamond products, high purity graphite materials and graphite products. For a long time, Exin Company has always adhered to the belief that Qingshan does not relax, and is obsessed with the research and development of superhard materials and products. It has won difficulties and never stopped winning recognition and praise outside the industry. After 20 years of pioneering and innovative, Exin has formed a strong production capacity. The subordinates have four branches and four technology research and development centers in two branches, which provide solid technical guarantee and intellectual support for product innovation and sustainable development. More than 500 employees, including more than 100 various types of technical personnel, with an annual output value of more than 100 million. At the same time, the company won dozens of honorary titles such as “Hubei Province Science and Technology Innovation Star Enterpriseâ€, “Hubei High-tech Enterpriseâ€, “Hubei Province Market Quality Assurance Enterprise†and “Contract-honoring and Credit Enterpriseâ€. It is well known that diamond is the hardest substance in the world, its industrial application value is extremely high, the technology content is high, the market demand is strong, and the profit space is large. Therefore, at the beginning of the establishment of Exin Company, it has locked its eyes on synthetic diamonds belonging to the high-tech industry. RVD synthetic diamond abrasives are classified according to the “newest national standards for diamond and diamond productsâ€, which means that the average single-grain compressive strength ≤19.6N (Newton), the particle size distribution is between 60#～120#, and the peak particle size is highlighted at 70#～ 100# This section of synthetic diamond single crystal. Driven by a keen market sense of scent, on the basis of extensive market research and practice, Exin Company has positioned its main products to be produced using “I-type diamond-specific powder materials†with patented core technology and unique BRVD synthesis process. RVD abrasive grade diamond. In order to make products more competitive in the market, Exin Company adhered to technological innovation, management innovation and product innovation in 2006, and studied the synthesis of powder materials required for BRVD synthetic diamonds and applied for national patents. The main direction is to give full play to the advantages of the company, avoiding the shortcomings of developing high-material synthetic columns, and do our utmost to overcome the synthetic RB powder column for BRVD diamond. Its core technology is the purification technology of graphite powder, powder particle size control, formulation optimization and verification, pre-pressure and granulation technology, vacuum sintering and deoxidation technology, stability and anti-oxidation technology. The patented technology was approved by the National Patent Office at the end of 2009. The advantages of the "I-type diamond-specific powder material" in this patent are mainly as follows: (1) The color of the synthetic crystal is good, the yellow is bright, and the crystal face is oily. (2) High single output and low manufacturing cost. Taking the Φ35.5 cavity as an example, the average single-production of batch synthesis is about 145 carats, and the sample is up to 150 carats. (3) The particle size distribution is concentrated, the peak particle size is prominent, 70/80# is about 20 to 25%, 80/100# is about 50 to 60%, and 100# is less than 10%. (4) The diamond in the synthetic rod has a uniform distribution and a high single crystal ratio. (5) Randomly sampled RVD (BRVD) synthetic diamond composite samples were observed under a 40X microscope, and a considerable portion of the diamond single crystals belonging to high-strength grades were clearly observed. (6) The product made of it has higher abrasion and better grinding effect. The type I artificial diamond special powder material is a kind of high-tech product. It breaks the six-sided top sheet catalyst and carbon sheet assembly synthetic diamond method that has been used for many years in China, and directly optimizes the powder carbon source and metal powder. The ratio is processed into a powder column for the synthesis of RVD synthetic diamond. At this time, the RVD synthetic diamond is not the RVD synthetic diamond of the time, and it is quite different from the RVD synthetic diamond before 2005. Unlike RVD synthetic diamond produced abroad, we use BRVD synthetic diamond for the time being, perhaps more precisely. Due to the excellent performance of BRVD synthetic diamond, it is deeply favored by European and American customers, and the market potential is huge. At present, the market demand is strong and the demand for products is in short supply. Brand is an area that enterprises nowadays focus on and explore. In this field, Exin also has its own understanding and actions. Over the years, Exin has always adhered to scientific and technological innovation, management innovation, market research, and going out to learn, please come in and exchange, set up a scientific research center, link with universities, develop new products, apply ISO-2000 for on-site quality control, set off A full participation of the company, leading the industry's persistent brand campaign. Through nearly five years of research and development, Exin has turned BRVD synthetic diamond into a branded product with patent rights. Its brand value is mainly reflected in the following aspects: 1 good quality, the color of BRVD synthetic diamond crystal is pure yellow; The rate and transparency are generally good and contain a certain proportion of high-strength diamond material. The tool made with it has higher wear and better grinding effect, and is favored by the European and American markets. 2 Low manufacturing cost, using RB synthetic diamond special powder synthesis column and unique process synthesis of BRVD synthetic diamond, the synthesis time is short, the single output is extremely high, and the manufacturing cost is relatively low. 3 The application field is wide, and the replacement of BRVD synthetic diamond with cubic boron nitride and silicon carbide is increasing, and the market potential is huge. Long-term planning promotes harmonious development. Essen believes that the synthetic diamond industry is an eternal sunrise industry. After the age of the Stone Age, the Bronze Age, the Iron Age, the Alloy Age and the Semiconductor Materials, the eternal diamond material era is about to leap. ! China is a major producer of synthetic diamonds, and its output ranks first in the world for many years. As the field of application continues to expand. The alternative improvement of cubic hardening materials such as boron nitride and silicon carbide is in the developing period of industrialized urbanization in developing countries, which account for 70% of the world's population. At present, the annual demand for synthetic diamonds in the world has been growing at a relatively fast rate since the financial crisis in 2008. The next 30 years is a good time for the development of the diamond industry, so we must make a long-term development plan. First, we must treat the eternal industry with eternal heart; Second, we must seize the opportunity to expand the territory; Third, we must establish a good credit relationship to improve capital utilization. The economic crisis has subverted the traditional business model. In the new economic environment, companies must find targeted income-generating methods. Growth strategies that used to rely on overall market growth to drive revenue growth are no longer viable. Companies should look for new revenue growth points, such as promoting value-aware products; improving marketing, sales, and service efficiency; engaging customers in digital channels; and establishing government partnerships. During the “Twelfth Five-Year Plan†period, Exin Company will establish the main business of diamond raw material production, with the synthetic production of diamond single crystal as the main feature, based on the expansion of the production scale of graphite series products, with high-grade diamond tool products as The overall plan for the direction of development. In the next 2-3 years, Exin's equipment production line will be fully upgraded, the process automation production level will be increased to 60%, and the technical equipment will reach the international leading level. And with its own research and development capabilities, efforts to improve the grade of diamond products, further improve the marketing network system, open up overseas markets, enhance sales capabilities, so that the company has become the most diverse and most comprehensive in the same industry in Hubei. Large-scale diamond products enterprise with the strongest capacity and high market share. After 20 years of hard work, the current sailing is booming, and now the history of the growth of Essen will be the beautiful myth that spread in China in the future.
